THE NAUTILUS. 117 



and more depressed [not umbilicatellus Ckll.]. These are fresh, 

 while all parvus are chalky. 



P. bicarinalus (Say), one juv. 



Physa, a few juv., very small, apparently of a small and slender 

 form. 



Helicina., probably orbiculata (Say), juv. only. Two opercula of 

 an Amnicolid. 



Paludestrina diaboli (Pilsbry). 



Pisidium limatulum (St.), one, immature; known from Alabama 

 and Mississippi. 



P. singleyi (St.), one adult and one juv.; known from Alabama to 

 Mexico. 



Eupera singleyi Pils. (?),one puerile, somewhat different from the 

 southern Texas ; less inflated, beaks pointed. 



Remarkable is the abundance of some Bifidarice compared with 

 the scarcity of others and of Vertigo ; also the total absence of 

 Vallonia. 



Drift material is a valuable asset for faunal studies, giving " point- 

 ers," and should be carefully collected wherever possible. It might 

 be suggested, by the way, that not too fine a sieve or strainer should 

 be used, one of about six meshes to the inch, although the siftings 

 may become rather bulky. 



But then local collecting should be done in order to have the 

 species and forms from their several habitats, the specimens fresh, 

 with the soft parts, for studying their relations. In the present in- 

 stance this would be desirable especially with respect to the small 

 Zonitidce, which appear to need a careful revision on good material 

 from many places. 



To Dr. Pilsbry I am indebted for the identification of some species. 



NOTE ON THE OCCUREENCE OF A GIANT SftUID OFF THE CALIFOENIA 



COAST. 



BY S. S. BERRY. 



Outside of Alaska the largest species of squid which has hereto- 

 fore been recognized from the Pacific Coast of North America is the 

 Dosidicus gtgas (d'Orbigny), which ranges north at least as far as
